Keibler is considered to be a sex symbol and is known for her unusually long legs.[6][8][9] She has been known as both "The Legs of WCW" and "The Legs of WWE".[5] During her time on Dancing with the Stars, judge Bruno Tonioli nicknamed her "The Weapon of Mass Seduction" because of her long legs.[11]

Keibler was born on October 14, 1979, in Rosedale, Maryland, the daughter of Patricia and Gary Keibler.[8][12] Beginning at the age of three, Keibler took ballet, jazz, and tap dancing classes at Jean Kettell Studio of Dance in Dundalk, Maryland. She went to St. Clement Mary Hofbauer School in Rosedale for her early schooling.[8][9]

In 1990, Stacy won the title of Miss Maryland Pre-Teen, after competing for the title in Timonium, MD, and went on to win the National Miss Pre-Teen Crown.

As the Fitness Editor at Stuff magazine during 2005 and 2006, Keibler wrote and modeled for her own occasional column, Getting Fit with Stacy Keibler.[7] She has appeared on the cover of that magazine twice -June 2005 and March 2006. Maxim named Keibler No. 5 in its 2006 Hot 100 issue, and No. 70 in its 2007 Hot 100.[6][14] In 2008, she was named No. 89 in Maxim's annual Hot 100 list.;[15] the following year she was No. 77.[16] In 2010, she was No. 82[17] and in 2011 she was No. 72. And in 2012 she was ranked 51.[18] Keibler has declined two invitations from Playboy to pose in the nude for its magazine.[8]

She competed in the second season of Dancing with the Stars, alongside her dance partner, Tony Dovolani.[19][20] Keibler received a perfect score of 30 from the three judges for her samba dance routine in week five.[5] This prompted judge, Bruno Tonioli, to nickname her a "weapon of mass seduction."[11] Overall, Keibler and Dovolani received four perfect scores.[5] Keibler was eliminated in the final episode,[19] coming in third to Jerry Rice, who placed second in the final round of the competition, and Drew Lachey, the winner of the season. Two of the judges, Bruno Tonioli and Len Goodman, felt she should have at least placed second.[21] Oddsmakers had considered her the favorite to win the competition.[19]

In April 2008 she was named No. 64 in FHM's annual 100 Sexiest Women list.[26] Keibler was featured in an advertisement in the 2008 Sports Illustrated Swimsuit issue. Keibler appeared on ABC Family's mini television series, Samurai Girl as the character Karen that September.[27] On November 23, 2008, Keibler was named the "World's Hottest Athlete" by a sixty-four contestant bracket on InGameNow.[28][29]

Keibler recently hosted the E! Special Maxim's Celebrity Beach Watch: 15 Hottest Bodies on September 16, 2009, and The Ultimate Spike Girl 2009 Finale on Spike TV on October 1, 2009. On January 11, 2010, Keibler appeared as "the hot bartender", a new conquest for Barney, in the How I Met Your Mother 100th episode, "Girls Versus Suits". On February 3, 2010, Keibler appeared on an episode of the USA Network show "Psych". Keibler hosted Call of Duty Elite's Friday Night Fights.[30]

Keibler began watching wrestling with her boyfriend at the time, Kris Cumberland.[9] She can be seen in the crowd on an episode of Nitro in 1997 and the Starrcadepay-per-view before the television title match, dancing in an NWO Wolfpac T-shirt.[35] In late 1999, Keibler entered a nationwide contest held by World Championship Wrestling to find a new member of the Nitro Girls dance troupe. In November, she defeated 300 other girls for a spot on the dance troupe and $10,000. Her winning routine was watched by 4.4 million viewers.[9] Keibler performed dance routines every week on WCW's flagship show Monday Nitro under the name Skye.[9] By 2000, Keibler was appearing on WCW as a Nitro Girl, attending school full-time, and cheering for the Baltimore Ravens.[9]

She soon accepted a larger role and became a valet using the stage name Miss Hancock (some weeks spelled "Handcock"),[10][36] briefly serving as an associate for the tag team of Lenny Lane and Lodi dubbed Standards and Practices.[37] Despite wearing business suits, her character was known to climb on top of the announcers' table and dance sensually.[10] It was also during this period that she began using what would become her trademark ring entrance: slowly putting her forty-two inch legs through the second tier of ropes, pausing to let the crowd momentarily see her panties.[38] At 5 feet 11 inches, Keibler was one of few women in professional wrestling tall enough to step over the middle of the three ropes that surround the ring.

For a brief period, she dated David Flair (both on-screen and off), who was already involved in an on-screen relationship with Daffney. This led to Keibler's in-ring debut at the Bash at the Beach in a Wedding Gown match, which she lost after she removed her own gown.[39] Hancock next briefly feuded with Kimberly Page, but the storyline ended abruptly when Page quit the company.[9][40] Keibler and Flair then began a feud with the Misfits in Actionstable, including a mud wrestling singles match against Major Gunns at New Blood Rising.[10][39] During the match, she was kicked in the stomach, and she revealed herself to be pregnant the next night, beginning a new angle for herself and Flair.[10] Two proposed endings to the storyline were for either Ric Flair or Vince Russo to be the father of her child.[36] The angle, however, ended prematurely, as she revealed the pregnancy to be false, broke up with David Flair, and was taken off of television.[11]

When she returned, she was known by her real name on-screen.[10] On the March 12, 2001 edition of Nitro, Keibler revealed Shawn Stasiak as her "baby." She helped Stasiak defeat Bam Bam Bigelow in the final edition of Nitro two weeks later on March 26.

When WCW was purchased by the World Wrestling Federation (WWF) in 2001, Keibler's contract was bought by the WWF. She portrayed a heel character in The Alliance. She made her WWF television debut on the June 14, 2001 episode of SmackDown! when then-face, Shane McMahon brought her to the ring to distract then-heel, Rhyno, causing him to lose a match.[41] Keibler originally teamed up with real-life friend, then-heel, Torrie Wilson, and the pair feuded with Trish Stratus and Lita. During this feud the four wrestlers competed in the first-ever tag team Bra and Panties Match at the Invasion pay-per-view, which Trish and Lita won by stripping Stacy and Wilson down to their bra & panties.[10][42]

Towards the end of the WCW/ECW Invasion, Keibler managed the heel gimmicks of The Dudley Boyz and was nicknamed the "Duchess of Dudleyville".[10] During this time, she began an on-screen rivalry with former ally Torrie Wilson after Wilson left The Alliance, with Keibler ordering The Dudley Boyz to put Torrie through a table, and taking great pleasure in her evil actions. Torrie, however, got her revenge after giving Keibler a wedgie then pantsing her on an episode of SmackDown!.[43] She then defeated Keibler in the first-ever lingerie match, a match wrestled in lingerie, at No Mercy.[42] Keibler made her WrestleMania debut at WrestleMania X8 alongside The Dudleyz.[42][44] Keibler's role with the Dudley Boyz came to an abrupt end when she was powerbombed through a table after accidentally costing the team a match.[45] She then set her sights on the WWE Women's Championship at Judgment Day, facing Trish Stratus in a losing effort.[46] She faced Stratus several more times in the succeeding weeks, but she never won a match against her.[11]

Keibler was originally drafted to the SmackDown! brand in 2002,[47] where her character showed an interest in becoming the personal assistant to WWE chairman, then-heel, Vince McMahon.[8] McMahon was ready to hire another attractive female until Keibler interrupted and performed a table dance in the ring.[45] Keibler became McMahon's personal assistant,[8] as well as his on-screen mistress. She was frequently shown flirting and 'making out' with him in backstage segments, until Stephanie McMahon became general manager of the SmackDown! brand.[48][49] Then-babyface, Dawn Marie made her debut on SmackDown! as McMahon's legal assistant, who competed with Keibler for McMahon's affections.[50]

A key storyline for Keibler's on-screen character occurred when she left SmackDown! for Raw. Keibler made her official Raw debut on August 12, 2002. For the remainder of 2002 and most of 2003, Keibler was paired with her real-life boyfriend at the time, Test. As Test's on-screen marketing agent, she came up with the idea that Test should call his fans "Testicles," cut his hair, and reshape his image.[51][52] The couple were originally villains but due to popularity of the gimmick, they became fan favorites. In the spring of 2003, Test, however, became to verbally abuse Keibler, who also started managing Scott Steiner. After months of build-up, Keibler finally left Test for Steiner on the June 2 edition of Raw.[53] Steiner defeated Test for Keibler's services at Bad Blood, and Keibler seemed happy as Steiner's new manager, as the two alluded to having more than a professional relationship.[54] Test, however, continued to harass Keibler and Steiner until Steiner accepted a rematch with Stacy's services on the line. On the August 18 episode of Raw, Test won the match after faking a leg injury and then blindsiding Steiner with a big boot. A match was then set for Unforgiven with the stipulation that if Test won, he would not only retain Keibler's services,[38] but would acquire Steiner's services as well. During the match, Keibler's interference backfired, and Test won the match.[55] Steiner then turned heel by attacking Keibler after her interference in his match on the September 29 episode of Raw backfired.[56] For a time, Test and Steiner worked as a tag team, sharing the services of Keibler as their on-screen sex slave.[38] The storyline finally ended on the December 1 episode of Raw, when general managerMick Foley freed Keibler from her obligatory contracts with Test and Steiner by temporarily firing them.[57]

Keibler was chosen to record a track on the album WWE Originals. She and WWE music producer Jim Johnston recorded the song "Why Can't We Just Dance?" for the album.[58] She was then placed in a feud involving Torrie Wilson and then-babyface, Sable, both of whom had recently posed for a Playboy cover. Keibler aligned with Miss Jackie, neither of whom had posed for the magazine, claiming that they deserved to be in Playboy over Sable and Wilson.[59] Keibler and Jackie challenged Sable and Wilson to a Tag Team Evening Gown match at WrestleMania XX, which they lost when Jackie was pinned by Wilson, and the feud was dropped afterward. Before the feud was dropped, all the performers were playing face characters at the time.[60]

On October 13, 2003, Keibler appeared in the ring with Steve Austin. She was offered a beer, which she politely refused. However, at the urging of Austin, she took a sip of the Miller Lite. Her disgust was apparent, which displeased Austin. As a result, she received a Stone Cold Stunner. The following week, Stacy proudly drank with Austin learning her lesson from the week before.

She took over the 2004 Raw Diva Search for a few weeks, which led to several tag matches against the heel gimmicks of Gail Kim, Trish Stratus, and Molly Holly and with partners Nidia and the face gimmick of Victoria.[11] Keibler got upset victories over Kim, Stratus, and Holly.[11] She earned a Women's Championship title match on October 11, 2004, but she was defeated by Stratus, who retained the title.[11][61] Keibler also competed in the first-ever Fulfill your Fantasy Diva Battle Royal for the WWE Women's Championship at Taboo Tuesday along with Victoria, Nidia, Gail Kim, Molly Holly, Jazz, and then-champion Stratus.[60] She was eliminated second to last after jumping over the top rope to avoid hitting the turnbuckle, followed by Holly knocking her off the apron to eliminate her.[60]

In February 2005, Keibler began appearing in backstage segments with then-babyface, Randy Orton, and eventually became his on-screen girlfriend.[62] When Orton challenged The Undertaker to a match at WrestleMania 21, Orton ended the relationship by hitting Stacy with an RKO, incapacitating her. He justified it by claiming he was demonstrating how ruthless he could be in order to defeat The Undertaker.[63]

After a long tenure on Monday nights, Keibler and Christy Hemme, were moved to SmackDown! on August 25, as part of a trade that brought Torrie Wilson and Candice Michelle to Raw.[65] On SmackDown! Keibler participated in lingerie matches and bikini contests.[11] After a short absence, Keibler began a short feud with Jillian Hall, which led to the two having a match on Velocity, which Keibler lost.[11] This would be Keibler's final match with WWE.[66] Keibler then asked for time off to appear on Dancing with the Stars.[19] During this time, Keibler's WWE.com profile was moved from SmackDown! to RAW, though she never made an appearance on the brand before leaving the company. Keibler's final mention on WWE programming occurred on the March 6, 2006 episode of RAW, where she was insulted by Candice Michelle for placing third on Dancing with the Stars during Michelle's unveiling of her Playboy magazine cover. After completing her stint on Dancing with the Stars, Keibler officially parted ways with WWE in July 2006 to move on to other endeavors.

Keibler began dating Future Ads CEO Jared Pobre[71] in fall 2013, though they had been friends for several years previously. They were married on March 8, 2014 in Mexico.[72] They have one daughter, Ava Grace Pobre, born on August 20, 2014,[73] and one son, Bodhi Brooks, born on June 18, 2018.[74]
